- you are bidding on a rare chair from the first series with a metal protective cap below the seat, which was made of plastic in the later years of production - you'll also notice two side arms on the underside that offer you the option to provide the chair with armrests - serial number of the shell: 137 - the legs are equipped with new plastic caps to prevent the floor from scratching Colour: black. Danish designer and nature lover Arne Jacobsen designed the butterfly chair in 1953 (3107). It became one of the most sold chairs ever. Nowadays there are several variants of this icon available, and the collection is called 'Series 7' by design manufacturer Fritz Hansen. One of the reasons this chair has become so successful is the ergonomic design that makes the comfort of the butterfly chair unexpectedly good. But in all its simplicity and elegance, the chair is also very attractive in terms of appearance. Due to the large selection of colours and finishes, this chair can be used in various interiors and surroundings. The seat itself consists of curved veneer wood and comes in various colours and finishes (lacquer, wood grain, maple, beech, etc.). The chair can also be upholstered with leather or another type of upholstery. There are various options with this versatile design that seems to have a timeless character. Arne Jacobsen has designed a great icon and he probably never realised what kind of impact his designs would have on a future generation of designers. Other examples of his successful designs are: 'the egg', 'swan' and 'ant'.
